Patent CA-2064567-A1 (CA)
Inventor: ROGERS WALTER J JR
IPC: A61K49/06
Filed: 1990-07-19
Abstract: Accordingly, the present invention is directed to biological compounds derivatized so as to contain at least one perfluoro-t-butyl moiety for use in fluorine-19 NMR and/or MRI studies. The perfluoro-t-butyl (PFTB) moiety is an excellent reporter group for fluorine-19 NMR/MRI. It is a source of nine magnetically equivalent fluorine nuclei which generate a single intense resonance for easy detection in spectroscopy or imaging. This signal is a sharp singlet, not split by neighboring nuclei or spread over a wide frequency range and eliminates any chance of ghost images which might arise from multiple resonances. These spectral properties ensure a maximum signal-to-noise ratio (S/N) for readily detecting this moiety. The foregoing allows either reduction in the concentration of the derivatized compound, ability to use MRI instruments with lower field strengths, a reduction in imaging times, or a combination of the foregoing as a result of this moiety producing a single, sharp, intense resonance. Additionally, the PFTB  moiety-containing compounds may be utilized to determine oxygen concentration in aqueous solutions present in animate and inanimate objects.

Abstract: Apparatus for conveying panels, such as vehicle body side panels to and from work stations located at spaced locations along a conveyor includes a panel support frame mounted on the conveyor for movement along the conveying path with the support frame in an elevated generally horizontal conveying position.  The support frame carries a plurality of mechanically actuable releasable clamps adapted to retain a panel engaged against a group of locator pads fixedly mounted on one side of the support frame.  A second group of locator pads movably mounted on the frame are normally biased into engagement with the panel at spaced locations around its periphery to hold the panel in a predetermined position laterally of the support frame.  The support frame mounts an actuator member coupled to all of the clamps to position all clamps in a panel clamping position when the actuator member is in a first position and to position all clamps in a panel release position when the actuator is in a second position.  A spring biased latch on the support frame normally locks the actuator member against movement from either of its positions.  The conveyor includes a manipulator operable when the support frame is at a work station to pivot the support frame downwardly from its conveying position to a downwardly inclined transfer position.  Actuating devices located at the work station are operable when the support frame is in its transfer position to release the latch, disengage the movable locator pads and shift the clamp actuator member between its first and second positions.

Abstract: The present invention provides a method and apparatus for enhancing and recognizing connected and degraded text. The enhancement process comprises filtering a scanned image to determine whether a binary image value of an image pixel should be complemented, determining whether complementing the value of thepixel reduces the sharpness of wedge-like figures in the image, and complementing the binary value of the pixel when doing so does not reduce sharpness. The recognition process may comprise determining primitive strokes in a scanned image, segmenting the scanned image into sub-character segments based on the primitive strokes, identifying features which characterize the sub-character segments, andcomparing identified features to stochastic models of known characters and determining an optimum sequence of known characters based on the comparisons through the use of Viterbi scoring and level building procedures.
